When trouble arises
■While towing
If the hybrid system is off, the power
assist for the brakes and steering
will not function, making steering
and braking more difficult.

chased at your Toyota dealer.
WARNING
Observe the following precau-
tions. Failure to do so may result
in death or serious injury.
■While towing
●When towing using cables or
chains, avoid sudden starts, etc.
which place excessive stress on
the towing eyelets, cables or
chains. The towing eyelets,
cables or chains may become
damaged, broken debris may hit
people, and cause serious dam-
age.
●Do not perform any of the fol-
lowing as doing so may cause
the parking lock mechanism to
engage, locking the front
wheels and possibly leading to
an accident resulting in death or
serious injury:
• Unfasten the driver’s seat belt and open the driver’s door.
• Turn the power switch off.
